【摘要】 目的 探究乳腺癌MRI的特征性表现与腋窝淋巴结转移的相关性。方法 选择2019年1月—2021年4月医院收入的70例乳腺癌患者作为本次的研究对象，其中有31例患者出现腋窝淋巴结转移作为观察组，其余39例患者作为对照组，对70例患者手术前均统一进行MRI检查，分析患者MRI的特征性表现与腋窝淋巴结转移的相关性，并对相关数据进行统计学分析。结果 观察组患者乳腺癌肿块短径及长径比值远远小于对照组，差异有统计学意义（P <0.05）；观察组肿块边缘早期强化率高于对照组，差异有统计学意义（P <0.05）。结论 通过研究发现乳腺癌患者其癌肿短径与长径之比越小，其腋窝淋巴结转移可能性越大；患者癌症肿块早期边缘强化率越大，腋窝淋巴结转移可能性越大。从本研究结果来看乳腺癌MRI的特征性表现与患者腋窝淋巴结转移与否有较显著的相关性，可以通过术前MRI检查对乳腺癌患者是否发生淋巴结转移进行提示，能够有效地为手术方案的制定提供依据，临床应用价值显著，建议进行推广应用。更多还原

【Abstract】 Objective To explore the correlation between the characteristic MRI features of breast cancer and axillary lymph node metastasis. Methods From January 2019 to April 2021, a total of 70patients with breast cancer in our hospital were selected as the research objects. Among them, 31 patients had axillary lymph node metastasis as the observation group, and the remaining 39 patients as the control group. All 70 patients were examined by MRI before surgery. Analyzed the correlation between the patient’s characteristic MRI and axillary lymph node metastasis, and perform statistical analysis on the relevant data. Results The ratio of short diameter to long diameter of breast cancer tumors in the observation group was much smaller than that of the control group, the difference was statistically significant(P < 0.05);the early enhancement rate of the tumor edge in the observation group was higher than that of the control group, the difference was statistically significant(P < 0.05). Conclusion The study found that the smaller the ratio of the short diameter to the long diameter of breast cancer patients, the greater the possibility of axillary lymph node metastasis;the greater the early edge enhancement rate of the cancer mass in patients, the greater the possibility of axillary lymph node metastasis.From the results of this study, it can be seen that the characteristic manifestations of breast cancer MRI are significantly correlated with whether the patient has axillary lymph node metastasis. Preoperative MRI can be used to indicate whether breast cancer patients have lymph node metastasis, which can be effective for the formulation of the surgery plan provides a basis, and the clinical application value is significant, and it is recommended to promote and apply.更多还原
